Daikin UK launches
indoor unit for low
temperature pumps
Daikin UK has launched a new compact
floor standing unit that integrates the
hydrobox and domestic hot water cylinder
reducing the installation and servicing
time whilst minimizing the unit’s footprint.
The new all-in-one floor standing indoor
unit, which is now available in the UK, is
extremely compact, combining the hot
water tank and indoor unit of the Daikin
Altherma heat pump into a sleek modern
looking appliance.
The unit requires minimal side clearance
and no rear clearance as all water and
refrigeration pipework connections
are located at the top of the unit. This
effectively reduces the installation
footprint by 50 per cent to 0.45m2.
Incorporating all hydraulic components
such as the circulating pump, expansion
vessel and back-up heater, installation time
is reduced, as only water and refrigerant
connections are required.
Solar-Log Hybrid
eControl-Box
The Solar-Log Hybrid eControl-Box allows
PV plants and diesel motors to work
together efficiently. The diesel motors are
used as a backup and for grid control. They
are always active with a minimum output.
When PV power is available, it has the
priority for consumption, for example,
at a hotel. At the same time, the diesel
generator is running with a minimal output
to ensure a stable power supply. When
there is not enough PV power available,
the diesel generator provides the rest of
the power needed.
With this solution, it is possible to
stabilize the grid while ensuring the
maximum amount of consumption from
PV energy.

Sharp launches 270W poly PV module
Sharp has announced the expansion of its
energy solutions portfolio, with the launch
of a new high-performance polycrystalline
photovoltaic (PV) module: ND-RJ270 (270
W). The 270W module offers the highest
power output and efficiency in the Sharp
poly module line-up.
This reflects a significant expansion of
the Sharp PV module range over the last
two years, which now sees the company
offering 15 different polycrystalline and
monocrystalline modules in total, in sizes
varying from 48 cells to 72 cells. Sharp
is now able to offer its reliable, efficient
energy solutions to more homeowners and
commercial customers.
The new modules have a low-iron solar
glass with anti-reflective coating, which
allows 95 per cent of the sunlight to be
used for the production of electricity, and
have a module efficiency of up to 16.5
per cent (270W), allowing homeowners
to generate more solar energy from their
roofs. The modules are also suitable for use
in cold regions subject to snow, with the
robust design able to handle a snow load
of up to 5,400 Pascal.

Manufactured in Germany, the safety,
quality and durability of the module has
been recognised with IEC seals and full
MCS accredited within the UK.

New Ultrasonic Heat
Energy Meters
The new Qalcosonic heat meter is MID
Class 2 Approved for RHI and billing
purposes for both heating and cooling
applications. Meter sizes from DN15 to
DN50 with BSP threaded and flanged
connections, Qp values range from
0.6 to 15 m3/hr with R100 dynamic
range as standard and R250 as an
option covering a wide range of energy
metering applications. Utilising ultrasonic
technology, the meter has no mechanical
moving parts, prolonging the life of the
meter and ensuring long term accuracy.
The meter benefits from pulse outputs
and a range of optional communication
modules; including MBus, Modbus, LON
and RF868 (Wireless MBus) making it
ideal for AMR applications and linking
with existing management systems. The
Qalcosonic offers an IP67 rated protection
on the flow sensor, which is standard when
purchased with the cooling application
option and also with Glycol applications.
The Qalcosonic stores the energy
readings for both heating and cooling in
separate displays, automatically changing
over when the temperatures change.
Along with the energy readings the meter
also logs hourly, daily and monthly values
useful for monthly billing and monitoring
of historical data.
